Brendan had played professionally for Rotherham Titans and for a team in Alghero, Sardinia, before moving to Rome, where he was playing for a local team, Capitolina.
His Irish ancestry had also enabled him to represent the Ireland Under-19s. He had recently given up professional rugby after landing a contract at the Food and Agricultural Organisation, which is based in the Italian capital.
"He had been here just a few months but he was already one of us," said Paolo Vaccari, the president of the Capitolina rugby club. "He was a great player, an exemplary professional."
Many of the Exiles Committee, as well as his contemporaries - both from the Exiles and fellow Ireland Under-19s who played alongside him - will remember him well with affection. He was a lovely, quiet man. May he rest in peace.
